About Richfield

Richfield grew out of the Carey Act irrigation era in south-central Idaho. The settlement was first called Alberta; after the Idaho Irrigation Company’s 1907 land opening, canals from Magic Dam reached the Richfield tract in 1910, and the town was incorporated in 1909. The Little Wood River supplied early household water and still runs near the city, while irrigated fields and open rangeland define the Lincoln County setting. Richfield’s Main Street history includes a bank, hotel, blacksmith, implement dealer, cheese business, and the newspaper that recorded the town’s early decades.

That agricultural foundation remains visible in current routines. Richfield School serves students in grades K–12, the city maintains two parks and a campground, and Outlaw Day has been held each June since 1954. The nearby Little Wood River and Craters of the Moon region expand the local map to fishing, camping, hiking, biking, and cave exploration. City water history is part of the story too: the 1913 pump house moved water from the river into the newly platted town. Richfield is a place where irrigation canals, school grounds, annual town traditions, and high-desert recreation all meet around a small agricultural center.
